Patent GB-227777-A (GB)
Title: Improvements in or relating to rotary tool heads for use in cutting rod material
IPC: B23B5/14
Filed: 1924-04-29
Abstract: 227,777. Bornemann, C. Jan. 19, 1924, [Convention date]. Turning.-In a rotary tool-head of the type in which the cutting tools c are pressed into the work by weighted levers k under the action of centrifugal force, each weight m is provided with a spring-pressed brake bolt n adapted to bear against a curved surface s, which is so arranged that the pressure of the bolt on the surface decreases as the weight moves outwardly. The braking effect is therefore greatest when material of large diameter is being operated upon while for material of small diameter it may cease altogether. The pressure of the brake bolt is adjusted by means of a screw plug r. An adjusting screw t may be provided on each weight m to vary the initial position of the cutting tools.

Title: Improvements in or relating to amplitude-limiters for electrical oscillations
IPC: H03G11/00
Filed: 1946-04-05
Abstract: 613,952. Valve circuits for radio reception. PHILIPS LAMPS, Ltd. April 5, 1946, No. 10603. Convention date, Nov. 6, 1941. [Class 40 (v)] In an amplitude limiter in which grid current flows in the control grid circuit, means are provided to maintain a constant mean anode current in order to compensate for the reduction in conduction angle with increased signal amplitude. The limiter shown in Fig. 2 has a large resistor in the cathode circuit so that changes in mean anode current are offset by changes in grid bias. An A.G.C. voltage is provided through resistor 6. The circuit of Fig. 3 uses a pentode valve operated in that part of the characteristic where the anode current varies with anode voltage. The values of the anode resistor 10 and the screen resistor 9 are such that a decrease in mean anode current is offset by a rise in anode and screen grid voltage. The value to which the output is limited may be adjusted by controlling the bias voltage on the suppressor grid.

Abstract: <PICT:0596330/IV/1> <PICT:0596330/IV/2> <PICT:0596330/IV/3> <PICT:0596330/IV/4> A machine for treating textile articles, e.g. for pre-setting stockings, comprises a treating chamber 1 with inlet 2 and outlet 3 at opposite ends, and pressure locks 11 and 12, for admitting the articles to and discharging them from the treating chamber, so constructed as to maintain the working conditions in the chamber, the mechanisms for operating the pressure locks and for transmitting the articles through the chamber being driven in appropriately timed relationship.  The pressure locks may comprise a vertical casing 13 with diametrically opposite openings 14 and 15 and a concentric hollow cylinder 16 formed with a single longitudinal opening 17.  The track T for the conveyance of the form carriers on slide blocks 27 is constituted by guide rails 26.  The pressure locks are provided with mechanism for receiving and ejecting the form carriers, consisting of a springloaded piston 30 and a catch 31 attached thereto.  The catch is loaded against the spring and released by means of a face cam 32 and a pin 33 attached to the piston 30 which works in the groove of the cam.  The cam loads and releases the catch once in every revolution of the cylinder 16.  In the case of the charging pressure locks the catch is released to eject the form carriers when the opening 17 in the cylinder registers with the inlet 2 of the chamber, and in the case of the discharging lock when the opening 17 registers with the opening 15 in the associated casing 13.  Between the track rails in the chamber 1 is a mechanism comprising a rod 38 reciprocated lengthwise of the track by means of a disc crank 41 engaging with a member 42 attached to the rod. At each end, the rod is provided with a springload slide 45 fitted with a depressible catch 46, and at the delivery end the slide is also provided with a lug 47 engaging with a trigger 48 during the travel of the rod towards the outlet 3.  An adjustable collar 49 is provided to trip the trigger 48, whereby to eject the form carriers from the chamber 1 into the discharge pressure lock. The slide blocks 27 which support the form carriers are moved through the chamber by means of the pins 51 on chain 50.  Pins 62 and 63 on the rails 261 within the chamber 1 engage with a slot in the slide blocks in order to turn the form carriers through 90 degrees during their passage through the chamber in order to increase the capacity of the machine.

Abstract: 831,998. Printing surfaces. RITZERFELD, W., and RITZERFELD G. April 2. 1957 [April 28, 1956], No. 10684/57. Class 100(2) [Also in Group XXXVI] A method of making a composite sheet suitable for use as a lithographic printing plate comprises electrolytically roughening the metal foils of two composite strips 7 of material, each strip comprising paper joined to a metal foil by a water resisting adhesive the composite strips being drawn through a common electrolytic bath and connected to a source of current in such a manner that the metal foils act as the electrodes of the bath. The outer surface of the paper is provided with a water repellant protection lacquer, and thickness of the composite strips is not greater than 0.1 millimetre, the metal foil being preferebaly aluminium or aluminum foil. The strips are drawm from rolls 6 over rollers 8, 9, the latter being connected to an alternating current source 34. The strips are guided by rollers 10 through a bath 23 of an inorganic acid electrolyte, e.g. hydrodhloric acid. The electrolyte may be continuously regenerated and replenished from a storage container 24 by a pump 25. After passing through after-treatment baths 30, 31, the strips are passed betweenrollers 21, 22 for pressing upturned oxide particles back into the metal foil surface, dried and cut into sheet by cutters 33. A cut sheet may be imaged by placing it on a base sheet coated with a fatty wax layer so that the wax layer lies against the electrolytically roughened metal layer. The assembly may then be inserted in a typewriter with the coated base sheet against the platen and the cut sheet is struck by the type.

Classes 75(1) and 126 In a radiation burner 1 comprising gas pervious envelopes 4 heated to incandescence by a gas mixture burning close thereto the outermost envelope being made of thin flexible material such as a wire screen, one or more perforated plates 8 or wire screens are inserted between the envelopes and the mixing chamber 10 of the burner, and the envelopes 4 are kept in close contact at points or along lines distributed over the burner surface or the envelopes 4 are clamped along their rim between flat clamping surfaces or the envelopes 4 are spanned transversely across an elongated burner. The burner shown in Fig. 1 is of rectangular shape and the envelopes 4 are clamped to a flat flange 2 by a rectangular frame 3. The perforated plate 8 is made of heat reflecting material and has openings uniformly distributed over its middle portion. A slide may be movable over the plate 8 to shut off the openings. Alternatively two relatively movable perforated plates 8 may be provided. A rectangular mixing tube 12 leads to the mixing chamber 10 and is fed with gas by a gas pipe 13 having a plurality of nozzles 14 or a discharge slit. In a modification a grate formed by longitudinal and transverse enamelled slats or a honeycomb grate is inserted between the wire envelopes 4 and the perforated plate 8. The lower edges of the slats are curved and engage the envelopes 4. The grate may be secured to the perforated plate 8 or it may rest on the envelopes 4 or it may be urged into contact with the envelopes 4 by means of screws threaded through the burner casing and abutting the grate. Some of the upper edges of the slats may not contact the perforated plate 8. The lower edges of the slats may have projecting lugs contacting the envelopes. In the elongated burner shown in Fig. 8 the envelopes are held taut by members 48 the upper ends of which are engaged by a leaf spring 49. The tube 45 has mixture discharge orifices 46 and is fed by a mixing tube (not shown) which may project coaxially or discharge laterally into the tube 45. In other constructions one of the envelopes is strong and curved and another envelope is stretched across it or the envelopes are welded or cemented in places to each other. In Fig. 9 a thin cooking plate 52 is welded to a rigid ring 50 having stiffening ribs 51 and made of a material of higher coefficient of expansion than the cooking plate. A radiation burner is mounted below the plate and the heat therefrom causes the ring 50 to expand and keep the plate taut.
